Welcome to the OpenWARP website

OpenWARP is an open source boundary element simulation tool based on the NEMOH code developed by Ecole Centrale de Nantes. OpenWARP and NEMOH provide the ability to determine the frequency dependent added mass, radiation damping, and excitation coefficients that describe the behavior of a floating or submerged body in a wave field. These coefficients are widely used in conjunction with the Cummins equation [1] to model the behavior of wave energy conversion devices, ships, offshore platforms, and other floating structures.

OpenWARP code development was performed by TopCoder with support from the National Renewable Energy Laboratory and the U.S. Department of Energy’s Water Power Program.

Code overview

The OpenWARP project adds a simple meshing capability and graphical user interface to NEMOH (see image below) and also incorporates several feature additions that are described in the Documentation section.
